HARVE STER-SEA'T SPECIFICATION forming part of Letters Patent No. 339,563, dated April 6, 1886. I

Application filed January 28, 1886. Serial No. 190,046. (No model.)

To all whom it may concern.-

Be it known that I, SYLVANUS D. LOOKE, of HOOSlOkFtlllS, in the county of Rensselaer and State of New York, have invented certain or in part applied to low-level machines.

The improvements consist in extending one of the transverse sills "beneath the elevator frame, which may be the-inner sill of the wheel-frame,beyond the rear sill and mounting thereon an adjustable seat; in the specific means for the adjustment of the seat; in a brace from the seatstandard hooking into an eye on the elevator-frame; in making such brace-rod adjustable, and in an improved socket for the seat-standard formed integral with a foot-rest.

In the drawings, Figure 1 is a perspective view of a machine embodying my improvements; Fig. 2, avertical section through the elevator transversely of the machine, and Fig. 3 a detail of the casting which supports the seat-standard.

The machine consists, primarily, of a platform, A, at the forward edge of which is arranged a sickle bar or cutter, and upon which the grain falls as cutthereby; an elevator-frame, A, rising from the platform to a point above the main drive-wheel,,and thence extending down on the opposite side; two supportingwheels, B and B, the former of which carries the principal weight of the machine and serves as the driving-wheel from which motion is transmitted to the operating parts, and the latter being the grain-wheel, and a strong frame supporting the apparatus on the axle of the drive-wheel.

The elevator-frame is braced by diagonal brace-bars a, arranged as shown; but this feature I have incorporated in the subject-matter of another application,filedin the Patent Office of the United States on the 11th day of May,- .1883, Serial N 0. 94,633, and will not further allude to herein. I

For the purpose of varying the height of cut, the machineis vertically adjustable upon the axle of the main or driving wheel,as-usual in machines of this class, the outer supportingwheel being likewise adjustable, in order to maintain the platform in a horizontal position.

The mechanism which I prefer to use for raising and lowering the machine is represented in Fig. 2,the axle being furnished with pinions meshing into segmental racks, alever being provided for rotating the pinions, and suitable detentsjbeingemployed for holding the 'pinions against rotation after adjustment, as in Letters Patent granted to me bearing date January 11,1881, and numbered 236,503, to which reference is made for a more full description.

In adjusting the machine to any considerable extent upon the driving-wheels its balance is changed somewhat, owing to the segmental outline of the standards in which said wheel is supported, and it is desirable to provide means to compensate for such change or for establishing proper balance when wanting from anycause. It is, moreover, desirable to place the seat lower down than has heretofore been customary,and in such position that the driver may see the binding-table as well as the grainplatform, and that his line of sight may strike the standing grain before the cutters at a very moderate inclination. For this purpose, and in order also to permit the various levers and other devices by which the different groups of mechanism are controlled or adjusted to be brought directly and conveniently within the reach of the driver, I mount the seat 0 upon the rearwardly-proj ectin g beam G,whicl1 runs longitudinally beneath the elevator-frame,the standard 0 of said seat being seated in a step, block, or casting c, which is adjustable forward and backward upon the beam, and is held at any desired adjustment by means of a bolt, 0 passing through the step or casting and through one of the series of holes in the beam. Thus 1ocated,the seat is convenient to mount, and the driver seated therein commands a view of the raking-platform and the binding-table on opposite sides of the elevator,

and a low-down view of the standing grain,

besides being in convenienuposition to reach the lever for raising and lowering the machine,

the device for adjusting the tongue, and the levers for varying the position of the reel.

.. The step or casting c is formed with an inclined socket to receive the seat-standard,and

' with a foot-rest, 0 to receive the feet of the driver. The standard may be bolted in the socket; but ordinarily its leverage will be suf ficient to confine it therein, and for the purpose of staying it when so confined and to permit its ready removal or adjustment, I provide a rod, 0, having its inner end bent to hook intoan eyeor staple on the frame of the machine, and having a series of perforations at its outer end ,to receive a hook or pin on the seat-standard bent at such angle that after the rod has been applied thereto and hooked into its eye on the frame it cannot be removed without'first releasing it from said eye.

It will be understood thatI do not herein claim the raking apparatus shown in the drawings, such constituting the subject-matter of the original application filed March 16, 1881, Serial No. 28,512, of which this is a division; nor do I claim the mechanism for adjusting the tongue, having made this the subject of a separate division of said original application filed January 28, 1886, Serial No. 190,045; nor yet do I claim the reel and its accessory devices, such being covered by still a third division of the parent application, numbered 190, 04.7 ,and filed on the date last above given; 3 5 but What I claim herein as my invention is- 1. In combination with the step or block c and the removable seat-standard supported therein, the hooked brace-rod running from the seat-standard to an eye on the frame.

2. In combination with the adjustable step or block a and the removable seat-standard supported therein, the brace-rod having a series of perforations at one end to take over a pin on said standard,and a hook at the other to take into an eye on the frame.

3. In combination with the rearwardly-extending wheel-frame beam 0', the seat 0, adjustable thereon, whereby the balance of the machine may be established and preserved;

4. The step or block c,formed,as described, with an inclined recess to receive the ,seatstandard and with the foot-rest 0, as shown.

5. In combination with the rearwardly-extending wheel-frame beam 0', provided with a series of holes, an adjustable block or step carrying the seat-standard, and a bolt adapted to pass through one of said holes and to secure the block or step to the beam.
